I have a NW pump from a CSS 220. Was going to use it as a feed pump in the recirc mode. Not sure what the flow rate is around 350 GPH ?? Any thoughts ???

You would want your flow rate to be approx. 1 to 1-1/2 times tank volume.

It does seem to be a bit on the Large side allthough I have heard of people using another sedra 5000 as a feed pump. I can ball valve it back some if I need to, I was just wondering mostly how an NW pump as a feed pump would work out and if anyone has done this with success??

 

[mfinn]

I'm doing it and I and I believe Charlie Davidson is doing the same.
Anything to add more bubbles.

If your pump is not too much bigger than the reccomended flow rate, I would think you would get added benefit from the extra buubles.
In fact, I may try a larger needle wheel pump as a feed pump than the one I'm using now.

 

[mg426]

If I am understanding ya correctly you are using a 2500 on a G4.

 

[mfinn]

I am using a sedra 2500 needlewheel pump as my feed pump on a G-4x with the recirc mod using a sedra 9000.
My tank is a 240 gallon tank with a 85 gallon sump.

That set up should rock pretty well.

I just joined the club and recieved my g1x this morning. Wow, what a sweet piece of equipment.

I put a little tank water in it, popped it in my sump, plugged it in, set the water level and it is making alot of foam.

However, after 3 hours it started making a funny noise. I just unplugged it and see no problems, what do I do now?

My G1X gets too much air in the impeller chamber causing it to make a screaching sound. Just put an air valve on the end of the hose to adjust the air/water mixture. The pump should run almost silent and produce tons of bubbles.

i have a g-2 on a 60 gal. how would i do a recirc mod. it came with a sedra 5000 as a feed. if anyone can let me know i would appreciate it greatly.
thanks,
lance

Take a look here WWW.asmskimmer.com under modifications

 

[60Cubed]

i found it already. thanks a lot though. would the recirc mod make that much difference? if so, why don't they come with it?

G4X Sedra (1) 9000 R/C. I have tried 3 different n/w feed pumps.. @350, 600, 1200 gph.. The genx 2400 (600) seemed to be the better of the 3 .
I plan to buy another sedra 9000, make it R/C then feed with the smaller pump. I would like to see @1.5-2x total volume as my feed. (but will move up or down, since I have the pumps to try)

I just received my G3 with the Sedra 7000 pump. I am witing on a piece for my sump so I can finish the plumbing and add water to the new system.

How do I determine the correct height for the skimmer and outlet?

I suspect that the box that the pump arrived in said KSP-7000, however, if you look at the pump itself it should be a Sedra 5000. This is normal.

Your going to add a second sedra 9000 and have two recirc. pumps?

You might want to rethink that. 2- 9000 on a G4.

I think your internal turbulance will be counter produtive for foam... Whats your goal? more air?

 

[rockdiver]

Got a G3 would anything be wrong if i added a pump that does 800gph? do not have the r/c mod?

[Charlie Davidson]

Thanks for input Roland. (I value your opinion greatly) Yes, more air bubbles and finer bubbles. The G4X (8"x30") skimmer body. It does really well with the (1) 9000 r/c and a gen-x 2400 n/w as a feed pump. (feed halfway up body)
But some reading--- has me thinking -- I may have too much GPH as a feed. even though it looks like its not too much turublance at neck.
N/Ws smaller than 600gph have really done nothing to improve performace, and the big gen-x 6000 seems to have improved out-put of skimmate ( but its some what tea-like) (and I believe way too much turbulance at neck)

 

[Charlie Davidson]

BTW, I just finshed letting the glue dry on the new discahrge piping- on my OR3700 (900) n/w. I plan to try it as feed pump today (2 weeks trial)

 

[Charlie Davidson]

Rockdriver, I believe that 2 smaller pumps set up R/C may be alot better that one big pump. IMHO..
